A purging apparatus for removing air from a fluid conduit is a burner nozzle which automatically purges air from the nozzle elements to limit post-drip of liquid fuel from the nozzle. The nozzle has a partitioning element(6) adjacent the burner tip(4) with at least one passage of limited cross-section which, in response to flow of liquid, disperses or atomizes air bubbles by picking them up and ejecting them through the nozzle tip.
